    window.addEventListener("resize",function(){
      if(window.parent.setIfHeight){
        window.parent.setIfHeight($("#children").height());
      }
    });

    $("#root").bind('DOMNodeInserted',function(e){
      if(window.parent.setIfHeight && window.parent.innerHeight < $("#children").height()){
        window.parent.setIfHeight($("#children").height());
      }
